"Feminism" means different things to different people. If you use "feminism" as a synonym for "gender egalitarianism", then that's not entirely incorrect, but you are picking a fight that will be full of straw man arguments, because other people use the word differently.
(I happen to share those values but I know people and entire societies with belief systems that don't.)
Like, it is kind of a coalitional word, I think. Of course, there are a number of ideas in common amongst the various ways it has been used,
and among those ideas held in common, are "women often experience unfair disadvantages due to how women are treated compared to men." and "that should be addressed/remedied in some way.",
and these statements are true.
But, the word "feminism" is not understood to refer solely to those statements held in common. If it was, there would be no such thing as different "waves" of feminism.
Rather, the word "feminism", at least often, is used to refer to "those claims made/supported by a coalition of people calling themselves "feminists".
(Personally, I try to avoid actually using the word "feminism", rather than referring to it, because I think that thinking of it as the name of "a thing" risks confusion which I'd rather avoid?)
I mean the discussion is about what constitutes a barrier, and how to prevent them, but the general sentiment that's still the core of the idea is unequivocally good.
Anything else?
I find that these views are spread not so much by strains of feminism or anyone seeking to improve society, as by the aforementioned people using feminist frameworks to justify their own takes on gender essentialism and bigotry.
I don't consider this feminism since it does nothing to improve anything for anyone, but yes, the lack of intolerance for misandry among feminist spaces is one of my big issues with it.
This is called the "No True Scotsman" fallacy. ("No true feminist would be intolerant or misandrous.")

I will agree that feminism is "unequivocally good" if we first define it thusly then discount every feminist who is less-than-good :)
